NaxRiscv Extensions

Hi,
I wanted to ask how much amount of work it will be to extend the NaxRiscv with a few custom instructions for AI, for instance, vector-matrix multiply? Thanks.

Hi,
So, if the inputs are regular register file, and output too, no new load and store, that's realy easy (ex SIMD on the int RF), that's just like one hour of work.

If things get more invloved, like new register file, As long as the load / store keep working like the actual FPU / INT ones, that's not too much a big deal, maybe 2 days of work,

If load and store are custom, that maybe way more work involved, like hell amount of work
